Got in a car accident years ago and the car rolled over 3-4 times so lower back pain/tightness. Would pop it myself and then it would tighten up again every few hours. Finally said fuck it, dude did an x-ray and then basically just one small adjustment that took 2 seconds. I scheduled an hour massage with chick right after he was done. Walked out to my car and damn near fell asleep. Combo of pop an hour massage lasted quite a few months of relief. Should have probably kept going back every 6 months or so but only went the one time.
On the flipside my dad went to a different guy and dude fucked him all up.
So guess ya gotta pick a good one.
